Reviews — Jukes-Browne's Student's Handbook of Geology. 279 



The present volume is illustrated by thirty-two plates of fossils, 

 geological sections, and views, including many effective pictures of 

 glacial and volcanic phenomena as well as of the stratigraphical 

 features in the sedimentary rocks. H. B. W. 



V. — The Student's Handbook of Stratigraphical Geology. 

 By A. J. Jukes-Browne, B.A., F.G.S., etc. Large crown 8vo ; 

 pp. xii, 589, with 1,000 Illustrations. (London : E. Stanford, 

 1902. Price 12.s. nett.) 

 ri^HAT there must be a fairly constant demand for textbooks on 

 X geology is evident from the almost perennial succession of 

 them, mostly by more or less well-known geologists. There is an 

 average sameness about them all : allowing for personal idiosyn- 

 crasies, their stratigraphy is ' correct,' while their palaeontology, 

 especially as regards nomenclature, is hopelessly out of date, and 

 their illustrations only too frequently as venerable as their subject. 

 Judged on these lines, this, the latest comer of the long series, is 

 a successful production. 



The present work, the author tells us in his preface, is a rewritten 

 edition of his " Student's Handbook of Historical Geology," which 

 was issued in 1886 as one of the celebrated " Bohn's Series." The 

 change of title in the present edition more accurately conveys the 

 scope of the work, which does not deal, as the old designation might 

 have led one to infer, with the history of the science itself. 



The general plan of the original book has been retained, but the 

 chapters dealing with the Palseozoic rocks have been expanded, and 

 the sections on Paleeogeography abridged, since this latter subject 

 has been more fully dealt with in the author's " Building of the 

 British Islands." 



Some previous knowledge of geology is indispensable to the student 

 of this volume, and for this he is referred to "any elementary manual 

 of geology " or "the author's Ifandbooh of Physical Geology." 



The nomenclature and classification of strata adopted by Mr. Jukes- 

 Browne do not materially differ from those employed in other 

 modern textbooks, he having wisely abandoned sundry variations 

 which he proposed in 1885 (Geol. Mag., 1885, p. 297) and incor- 

 porated in the former edition of this book. He does, however, 

 introduce the term ' Selbornian,' coined by him in 1900 (Geol. Surv. 

 Memoir, "The Cretaceous Eocks of Britain," vol. i), to include the 

 Upper Greensand and Gault; and for this term there is some 

 justification. 



A glance at a modern table of strata brings to mind, with 

 amusement, Ramsay's " Lament for the Good Old Days of William 

 Smith," when 



" Our ancient English was the law 

 In geologic volumes." 



We have advanced far indeed in the importation of foreign terms 

 since then. 



After the introductory portion comes the main body of the work, 

 in which each system is made the subject of a chapter.
